Hi there,

I am looking at buying some rotors for a 20B turbo build.

I am wanting to buy them brand new and I have noticed that no one seems to sell new 20b rotors. I am not too sure if they are any different from any of the 93-94 RX7 rotors at all...

Are there any preferred rotors that I should be looking at getting? What compression is available from the various models?

I am not interested in the billet ones that are being made.

Thanks

 

FD and 20B rotors are the same, they are 9:1 compression ratio. The S5 TII rotors are the same ratio and can also be used.

Some people that have plans of running super high boost like to run the S4 TII rotors that are 8.5:1 compression. These rotors are heavier and have thicker castings, the rotor faces do not dent as easily from heat and detonation.

 

Thanks for that.

They retail for $1,100 AUD here in Australia...

Cheapest i've found in the USA is $680USD!
